-The objective of this work was to determine the inheritance of resistance by antixenosis in tomato plants (Lycopersicon esculentum) to tomato leafminer [Tuta absoluta (Lepidoptera: Gelechiidae)]. Evaluations were performed for tomato plants of the generations P 1 , P 2 , F 1 , F 2 , RC 1 and RC 2 . The measured characteristic in the parents, BGH-1497 (P 2 male) and 'Santa Clara' (P 1 female), and in the F 1 , F 2 , RC 1 and RC 2 generations was the number of eggs per plant. This number was converted to the oviposition nonpreference index. The inheritance of antixenosis resistance of genotype BGH-1497 is ruled by a gene of greater effect and polygenes in epistatic interactions, with a phenotypic proportion of 13:3 between susceptible and resistant genotypes, respectively.
